This invention relates to a lock designed primarily for use on barndoors and the like where they are exposed at all times to the action ofthe elements.

It is an object of the invention to provide a lock which canbe packedwith a lubricant which serves not only to keep the parts in properworking Condition but also acts to prevent the ingress of moisturethrough the lock. 7 K v With the foregoing and other objects in viewwhich will appear as the description proceeds, the invention resides inthe com binat-ion and arrangement of parts and in thedetails ofconstruction hereinafter described and claimed, "it being understoodthat changes in the precise embodiment of the invention herein disclosedmay be made within the scope of what is claimed without so departingfrom the spirit of the invention. In the accompanying drawings thepreferred form of the invention has been shown. In saiddrawings Figure 1is an elevation of the lock, the same being shown in position on a door,a portion of which has'been illustrated. v

a Figure 2 is a section on line 2-2, Figure 1. Figure 3 is a section online 33, Figure 1. Figure 1 is a section on line H, Figure 3.

Figure 5 is a perspective view of the inner V bushing ofthe lockspindle.

Referring to the figures by characters of reference, 1 designatesa' lockhousing which can be providedwith a flange 2 bearing against a baseplate 3, both the base plate,

. and the housing being held to a door D by screws extending through theflanges 2 and the base plate. r

" A bolt 4 is extended from the housing and itis preferably madeintegral with a slide 5. A stem 6 may be extended from the slide andworks within aguide 7, there being a spring 8 on the stem for holdingthe bolt 4 normally projected where it will engage a keeper K. V

A sleeve 9 is journaled atone end in the housing. 1 and'at its other endin the plate 3 and carries wings 10 for engagement with the slide'5whereby when the sleeve is turned in either direction the slide will beshifted against the action of spring 8 so as to draw bolt 4 from itskeeper K.

The door D is provided with a tapered opening cl in which is tightlywedged a tapered outer bushing 11 which extends from one side to theother of the door D.

Rotatably mounted within the bushing 11 is an inner bushing 12 which isshaped to fit snugly in the bushing 11 and has a plurality oflongitudinal openings 13. A spindle 14; is rotatably mounted in thebushing 12 and has a head 15 at one end while its other end is screwthreaded as shown at 16. That portion of the spindle adjacent to thehead is angular in cross section as shown at 17 and is seated in thesleeve 9 so that when the spindle is rotated said sleeve will alsorotate.

The angular portion 17 of the spindle extends through a correspondingopening 18 formed in the straight side 19 of a handle 20 which ispreferably substantially semicircular.

The screw-threaded end of the spindle is engaged by a nut 21 having anangular por- 7 door D. I

Openings for the reception of grease or other suitable lubricant can beprovided at any points desired. In the drawings such openings have beenindicated at 28 in the walls of the housing 1, and are normally closedby screws 29.

After the lock has been assembled with a door in the obvious way, greasecan be forced thereinto under pressure and will fill all spaces withinthe lock. This grease will serve not only to keep the lock thoroughlylubricated at all times, but will also prevent moisture from gettinginto the lock. In other words, the grease acts as a packing as well as alubricant.

What is claimed is:

A look including a casing constituting a grease container, said casinghaving it normallyrclosedopeningja bolt lidable in the I casing, asleeve journaled in the casing and operatively connected to the bolt, atapered tubular bushingiforinsertion into a door or Y the like; and aslotted inner bushing rotatable inthe tapered bushing for receivinggrease" from the sleeve and housing, a spindle secured in the slottedbushing and sleeve and r0- Q tatable with the sleeve, and operating han-5 dles fixedly secured to thefrespective end por-- .tions of thespindlefo-r holding the housing;

and'bushings in abutment. In testimony thatI claim the foregoing as 5 myOwn, I have hereto afiixed my signature.
